It is aerobic respiration? Glucose is completely oxidized to carbon dioxide and water through glycolysis, trixacrboxylic acid (TCA) cycle and oxidative phsphorelation ATP release some energy and heat. In this context, is the byproduct heat!

The answer is that energy is released. A combustion reaction is a reaction with an organic compound with oxygen, carbon dioxide and water. This is an exothermic reaction (heat is released). So if you re-write the chemical equation to be the heat on the intake side, which means it is a byproduct of the combustion reaction.
